5.0 Programming Interface
AU9510 is a dedicated single chip USB SmartCard reader controller. In addition to silicon
itself, Alcor Micro provides WDM drivers on Windows 2000 and Windows 98 platforms to
ensure Microsoft PC/SC compliance. However, for non-Windows application platforms,
software driver developers may wish to access the reader directly. This document describes
Alcor’s vendor unique USB commands. Table 1-1 shows all commands. (For details of the
USB request specification, please refer to USB spec. Chapter 9 )
AU9510 Vendor Unique USB Requests

Device will perform a “warm reset” and return two bytes data. The first byte indicates the
ATR byte length and the second byte returns 00000001B if TA2 present (specific mode of
card operation). Following this command, host can use Endpoint 2 (Bulk Transfer) to get
ATR information. The number of bytes to transfer is indicated by “ATR Length”.

6.5. Crystal Oscillator Circuit Setup for Characterization
The following setup was used to measure the open loop voltage gain for crystal oscillator
circuits. The feedback resistor serves to bias the circuit at its quiescent operating point and
the AC coupling capacitor, Cs, is much larger than C1 and C2.
